'TnLEsoorio FISHING Ronf Application filed October 14, 1924. 'Serial No. 743,527'.V

To a-Z'Z wh om it may concern Y Be it known that I, CHAnLEs A. TREDWELL, a citizen of 'the United States, residing at New Haven, in the county of New Haven' and Stateof Connecticut, have invented a new and useful Improvement in Telescopic.

Fishing Rods; and l do hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full,V

clear, and exact description of the same, and which said drawings constitute part of this application, and represent, in-

Fig 1 a broken view, in side elevation, of a r telescopic fishing-rod, constructed in accordance with my'invention.

Fig. 2 a view thereof dinal section.

F ig. 3 a view` thereof, on a larger scale, in transverse section, on the line 3 3 of Fig. 2. Fig. 4 a corresponding view on the line l--Ll of Fig. 2, on the same scale asy Fig. 3.

in central, longitui the upper end of one of the joint-sections of the rod.

Fig. 7 a view, in rear elevation, of the lower end of the jo-int section, as shown in F ig, 6.

Fig. 8 a perspective view of one of the guide-collars. l' i Fig. 9 a view corresponding to Fig. 6, but showing a modification thereof. Y Y My invention relates to an improvement in telescopic fishing-rods, the object being t'o efficient construction for the production -of the friction required tomaintain its several joint-sections in their extended and telescoped relations. y

With these ends in view, my invention consists in a telescopic fishing-rod charac- 4terized by cylindrical joint-sections having the lower end of each expanded conically on the line of the seam and thus enlarged `in diameter, such expanded portion of the jointsection being slightly flattened on the seam for frictional engagement with the complementary joint-section in which it has telescopic movement, whereby the friction is reproduce a rod having a cheap, simple and;

moved from, the corners at the end of the seam. ,y L y My invention further vconsists in a telescopic fishing-rod having Ycertain detailsjof constr-uction -as will behereinafter described Vand 'point-ed out in the claims.

In carrying-out my invention, as herein .'shown, each joint-section 10 of the rod, barring the butt-section, has its seam 11 eX- panded at its lower end, as at 12, whereby the joint-section at said end is enlarged. The expanded lower slightly flattened along 'the seamY on each side thereof in the direction of the diameter which passes throughy kthe seam, as at 13, whereby the corners 14 of the metal are withdrawn from contact with the inner wall of the complementary.joint-section, as sh-own at 15 in Fig. l3 and prevented from abradend of the joint is thenl ing or grooving such 'surfaces of the y complementary joint-section, so as to rapidly decrease p the friction hold between the joint-section.' At the outer. end o-f the expandedlportion of each jointsection, I braze on aVguide-collar 16, dimensioned to have an easy sliding fit `inthe complementary joint-section, so `as to .increase the guiding surface between the two joint-sections. To increase the guiding surface between any two complementary jointsections, the upper end of eachsection is reduced in diameter for the `production of a guiding-sleeve 17 having an easy sliding lit,

Vas shown in Fig.12, over the main portion vof the complementary joint-sectio-n. The production of the sleeve 17 results in the formation of a cone 18`between thesame and f kthe main bodyfo-f the joint-section. r"This cone co-operates with the outer'end 19 of the guide-collar onthe complementary section, x

so as to form a stop to prevent the separation y of the sections,ias shown in Fig. 2.v A band 20 is brazed upon the sleeve 17 of each secguide 21. l l

'In the modification shown by Fig. 9, the joint-section 10, after the expansion of its seam 11 at its lower end, as at 12, is subjected to the action of suitable formingtion for the carriage of the` usual line-1 tools, whereby a substantially cylindricalv bearing-surface 22 is formed at the lower end of the section, so as to apply the friction, v

over a surface, inetead of upon a line of contact. Thus, in this modified form, the surface 22 makesV Contact throughout its lengthl with the inner Wall of the complementary section.

I claim:

Y l. In a telescopio isliing-iod, the combination with a longitudinally-seamed, cylindrical joint-section having'ite lower end conioally expanded along its seam and slightlyV 'flattened on veach side thereof, of a guldecollar fastened upon the said joint-section at the upper end of its said expanded and flattened portion; and a complementary jointsection in which the expanded and flattened lower end of the oint-section rst mentioned has sliding bearing.

2. In a telescopic fishing-rod, the oombination with a longitudinally-seained, cylindrical joint-section having its lower end oon- Lef/wei ieally expanded along its seam and slightly flattened on each side thereof, of a guidecollar mounted upon the said joint-section at the upper end of its said expanded and fiattened portion; and a complementary jointsection having its upper end reduced in diconically expanded along its seam and shaped y to forni a Substantially cylindrical frictioneurface slightly flattened on each Side ofthe seam.

In testimony whereof, I have signed this specification.

CHARLES A. TREDWELL.
